moivn that I, il oriN l l iii r "Inclt -n of the United States of America, res at Norfoll in the count a to which it appertains to make and use the less so than is now consumed by the prevale method of placing a stencil upon the article to he stencilled and painting; by hand over the same,

lt likewise an object of the invention to provide a machine of the character mentioned adapted to effect the automatic inovinn; of the particular stencil being; en'iployed by past the ink or paint supplvine; and a uil rh means Whei when the machine moved over the su "race to he stencilleth the desired matter Will he properh placed thereon.

"rnother and equally important oleiw of the invention is to provide one o the receiving rollers or drums with an auto inectie hralre means whereby whe the stencil has been completely transferrerh further nioven ent of the strip from the feeding; roller or drum will be prevented and in. con sequence rupturin or d ain aging; of the same prevented.

Other objects Will he in part obvious and in part pointed out hereinafter in order that the invention and its mode of operation may be readily understood by pen-wins skilled in. the art I have in the accon 'mny ng illustrative drawings, and in the detailed following); description based thereon set out one possible embodiment of the same.

In these drawings:

l? gure an enlarged fragmentary detail in vertical section showing the mounting of one of the vertically slidable pins With the ring in spiral Way of the adj acent roller;

Figure 6 is an enlarged fragmentary detail in tmnsverse section through the 1nount ing of the connecting pin; anch Figure 7 a fragmentary detail in ele" vation showing the manner in which the pin receiving; collar is slidahlv engaged and mounted.

Having; more particular reference to the draiviu in connection With which like characters of referencewill desigi nate correspondingparts throu ehout the improved machine may be stated to comprise a housing 1 substantially rectangular in shape and having the bottom thereof open, as clearly shown in the Figure 1. A knob or hand piece arranged upon. the upper side and for- W: d end of the housing, While anggle brackets arranged upon the upper side of the rearward portion of the housing; and pivotall support therebetvveen a hand grip or handle 4t.

ltiousinn or supporting: rollers or Wheels 5 are nmuntedv upon the inner ends of stub axles 6 secured to the opposite side portions ho one: 1. intermediate their ends and as will he noted" have the lower portions thereof extended slightly beyond or below the lower portion of said housine, whereby to provide a movable support for the same in order that it inav be freely moved over a surface to he stencilled. To the inner side of one of these whee-ls 5, there is secured a circular gear 7, screws 8 being passed through portions of the rear into engagement with eornplernentall screw threaded openings formed in the Web portion of said Wheels receiving; the same; the gear being of a diameter sli rhtlv less than that of the Wheel receiving; it and serving for a purpose which will he hereinafter more fully described.

Rotatahly mounted in the opposite ends of the housing 1 and arranged Within the same are transversely disposed rollers 9 and 10. formed of rubber, composition or other suitable material and having tread members 11 arranged upon the opposite extremities thereof for an obvious purpose,

Each of these rollers 9 and 10 are hollow and the roller 9 has a clock spring 11 arranged within the same as shown in the Figures 1 and 3 and the outer end of said spring is secured to an adjacent portion or the roller as indicated at 12, while the inner end of the same is secured to an adjacent portion of the side supporting it, as indicated at 13. Thus, it will be understood that with rotation of the roller in one direc tion, the clock spring 11" will be placed under a tension such as will cause rotation of the roller in an opposite direction with disengagement of its tread elements 11 from a surface over which the machine is travelling.

A stencil strip of pliable or flexible material, not shown, is adapted to be employed in connection with the machine and is adapted to be normally coiled or wound about the intermediate peripheral portion of the supplying or feeding roller 9 and to effect connection of the inner end of said stencil strip with. the roller, I provide said roller with a longitudinally disposed peripherally arranged clamping plate 14 having spaced dovetail shaped lugs 15 arranged upon the upper side ot' its opposite end portions adapted to be sli daoly engaged. in the longitudinally disposed dovetail shaped groove of a moveable clamping strip 16. Thus, when the inner end of the stencil strip is engaged between the clamping plates 14: and 16 positive connection as between the inner end oi the stencil strip and the roller 9 will be etfected. To limit the extent of sliding ongagement of the clamping plate 16 with the lugs 15 of the plate 14, a stop pin 1'? is preferably engaged with one end of the plate 14 and is received in a pocket or recess 16 in the corresponding end of the plate 16.

That end of the roller 9 opposite to the one receiving the spring 11' in it has formed in the end wall thereof, a spiral groove or way 18, the inner end of said spiral groove being arranged at a point adjacent the engagement of the axle of the roller therethrough, while the outer end of the groove arranged at a point in proximity to the peripheral portion thereof. I

An elongated slot 19 is formed in the corresponding portion of the adjacent side wallot the housing 1 and has secured adjacent thereto, a substantially rectangular guide bracket 20 slidably receiving a collar 21 therein which. as will be noted, is pro vided with oppositely disposed fingers 21. which are adapted to be engaged .in guide grooves formed upon the opposite sides of said bracket 20. An anchoring'plate, cor responding in shape and design to the plate 20 and indicated by the numeral 20 is secured to the opposite or inner side of the adjacent wall of the housing 1', common fastening means, such as rivets, screws or the like serving to interconnect both plates 20 and 20 through the adjacent portion of the side wall of the housing. Loosely engaged in the opening formed in the vertical slidable collar 21 is a pin 22, of a length such as will permit the inner end thereof to be engaged in an adjacent portion of the spiral way or groove 18. To prevent outward lateral movement of said pin with respect to the collar 21 and hence, disengagement trom the spiral way or groove 18, a cur ed spring plate or arm 23 is pivoted to the upper end or bracket 20, as shown in the Figure 5, the lower end of such spring arm being engaged over the headed outer end of the pin 22 and in consequence, retaining the same in its innermost position with respect to the collar 21 and therefore, engaged with the spiral groove or way 18.

Because of the engagement of the inner end of the pin 22 in the spiral way or groove 18, it will be understood that with rotation of the roller 9 in one direction, the vertically slidably mounted pin 22 will be permitted to ride upwardly in the bracket plate 20 and follow the spiral way 18 until the outer end thereof is reached. At this point, further rotation of the roller 9 in the aforesaid direction will be prevented and in consequence, an effectual form or check will be provided for by the rotary movement of said roller. Hence, excessive unwinding of the stencil strip from the roller 9 with the resultant probable tearing or rupturing oi" the same will be avoided. 9 is rotated in an opposite direction, the pin 22 now in its uppermost position in the plate 20 will be permitted to move downwardly in the bracket plate 20 until the same engages the inner end of the spiral groove or way 18, thus checking or limiting the rotative movement of the roller in this latter direction and in consequence, preventing the possible or probable tearing rupturing of that portion of the stencil strip secured to the receiving or stencil strip removing roller 10, hereinafter more fully described. In order that the rotative movement of the roller 9 may be varied, I may and preferably do form openings or pockets 24 in the bottom of several portions of the spiral way 18 and when desired, insert stop pins or plugs 24 therein, against which the inner end of the pin 22 will abut and thus, limit or regulate the rotative movement of the roller 9.

A receiving or stencil strip moving roller is constituted by the roller 10, which, as will be noted, is provided with an end wall having a spiral way or groove 18 formed there in corresponding to the spiral way 18 and in which the inner end of a connecting pin corresponding to the pin 22 having vertical When the roller slide-hie mounting in the adjacent portion of the corresponding side wall of the housing 1 is engaged, Thus, it will be understood that the rotative movement of the roller 10 will be limitedby the engagement of the connecting pin with the opposite end of the spiral way or groove 18. Furthermore, pockets 24* are formed in the bottom of cer-- tain portions of the groove 18 and are adapted to receive in either thereof a stop pin 243 corresponding to the pin 24 described in connection with the roller 9.

A stencil strip connecting device in form of slidably inter-engageable clamping plates 1.4. and 16 is arranged longitudinally of the peripheral portion of the roller 10, such ar rangement corresponding to the clamping means noted in connection with the plates 14 and 16 of the roller 9. These clamping plates 14 and 16, arranged upon the roller 10, as will be understood serve as means for effecting connection between the free end of the stencil strip and said receiving roller 10 whereby the strip may be caused to un-- wind from the roller9 and to wind about the intermediate portion of the receiving roller 10, such movement of the stencil strip from the supplying or feeding roller 9 to the receiving roller 10 causing the former roller to be rotated in a direction such as will place th clock spring 1.1 within the same under tension whereby when said feeding roller is disengaged from the surface over which the machine is travelling, it will immediately function to cause reverse rotation of the feeding roller with the resultant rewinding of the stencil strip about the same to render the machine ready for a further stenciling operation.

A hollow vertically disposed and slidable shaft 26 is mounted in the intermediate portion of the upper side of the housing 1 and as will be noted, has a portion thereof. formed substantially squared in cross sec tion; the upper end of the shaft being normally extended about the upper side of the housing top as shown in the Figure 2 and having a collar 26 movably engaged therewith, while upon the lower extremity of the veitically slidable hollow shaft 26, there is formed a shouldered screw threaded extension 27 which is adapted to be engaged in the cover plate or closure of the hollow head or reservoir28 of the fountain. feed or supply brush, the bristles of which are indicated. at 29, and as shown, are suitably engaged though a screw threaded fastening ring to the under side of said hollow head or reservoir 28.

Splined to the squared portion of the vertically nioveable hollow shaft 26 and arranged within the housing 1 is a bevelled gear 30 meshing with a corresponding gear 31 mounted upon the adjacent end of a transversely disposed horizontally positioned shaft mounted in bearing brackets 33 secured to the under side of the housing top as shown in the Figure 2 and having the outer ends thereof engaged in suitable hearings in the corresponding side wall of said housing:

a pinion 34: being fixedly mounted. upon the outer end of said shaft 32 and meshing with the circular gear 7 secured to the inner side of the adjacent wheel 5 As stated, the hollow shaft 26 is adapted to have vertical sliding movement with respect to the housing supporting the same and in order that it will be guided in such movement, there is secured to the adjacent portion of the under side of the housing top 1, a substantially U-shaped bracket 26 having an opening formed in its basal portion for receiving the lower portion of said hollow shaft 26 therethrough, while its free extremities are provided with angularly disposed feet 26 receiving suitable fastening devices therethrough, which in turn, are also engaged with adjacent portions of said hous-- .ing top. A coiled spring 27 is interposed between the outer and lower portion of the handle 4;, and the top of the housing 1 and serves to impart an upward thrust to the handle and the shaft 26 and in consequence. hold the latter together with the fountain supply brush in their uppermost positions within the housing 1.

Extended through the hollow shaft 26 is a needle valve 35, the lower end of which is adapted to be normally engaged in a dis charge way or port 36 formed in the lower side of the reservoir 28 of the fountain supply brush whereby to prevent the discharge of ink, or paint, or other marking material therefrom. The upper end portion of this needle valve 35 is screw threaded, as indicated at 37, and is adapted to be turned into engagement with an adjusting nut 38 an ranged upon the upper side of a substantially U-shaped bracket 39 secured to the upper side and intermediate portion of the housing top as indicated at 10, a. head or finger piece 4-1 being carried upon the upper end of said needle valve whereby to facili tate engagement and rotation of the same.

Thus, is will be understood that by reason 4 of the screw threaded engagement of the needle valve 35 with the adjusting nut 38, its relative positioning with respect to the discharge port 36 in the reservoir 28 may be varied, such as conditions or preference may dictate, as for example, to decrease or increase the flow of marking fluid from the reservoir onto the brush bristles 29.

A short tube 2-9 is embedded in the rub her or other composition employed in securing the hrush bristles 29 in the externally screw threaded securing ring, heretofore mentioned, nd as will be noted, is adapted to have the upper end thereof arranged at a point directly adjacent andbelow the port ing of said n other fountain feed bri has an internally screw threaded circulaflange 28 formed adjacent the upper side thereof, which inter nally screw threaded flange is adapted to be turned into engagement with the correspondingly screw I threaded lower portion of the reservoir of the fountain feed brush 28. as shown in the Figure 2.

Fin'thermore, diametrically d sposed fingers 28 may be and preferably are secured to the outer side of the bottom of the reservoir of the fountain feed brush head and obviously. serve as means for facilitating the connection of a spanner wrench or similar tool thereto whereby said bottom of the reservoir may be tinned into engagement with the screw threaded portion or out of engagement therewith. as may be required.

cecured to the opposite sides of the pivotally mounted hand grip 4: are arms 5 .2 carrying plate 43 upon their inner ends said plate having bearing upon the rounded upper end of the slidable hollow shaft 26; an opening being formed in the plate 43 whereby to permit the passage of the needle valve 35 tlieii'ethrough into engagement with the adjusting nut 38. hercinbefore identified.

Felt or other absorbent rollers 44 are disposed transversely of and within the opposite ends of the housing 1, being mounted upon hollow shafts 45 likewise extending transversely of said housing and having their opposite ends journalled in suitable bearings formedin the adjacent portions of the opposite side walls of such housing; it being noted in this connection, that the positioning of the rollers 44 and their respective shafts 4.5 is such as to bring the former directly adjacent the peripheral portionsof the rollers 9 and 10 and thus serve to remove any surplus of ink remaining upon the stencil strip employed subsequently to or immediately following a stenciling operation.

The operation of my improved steneiling machine may be reviewed as follows:

A stenciling strip is coiled about the feeding or supplying rolle 9, the inner end there of havin been secured to said roller through the medium. of its clamping plates 14 and 16. The free end of such stencil strip is now pulled from the roller .9 longitudinally of the housing 1 and over or past the bristles 29 of the fountain feed brush, whereas said free end of the stencil strip is engaged with the receiving roller 10 through the medium of its particular clamping plates Hand '16. With the stencil strip so connected, it is to be noted that the vertically sliable pins 22 engaging in the spiral ways or grooves 18 and 18 of the rollers 9 and 10 respectively will be at points adjacent the inner ends of such grooves. The machine is now ready for use.

Atthis time, the hand grip e is engaged in with. the adjacent side of that portion of the stencil strip spanning the space between the feeding roller 9 and the receiving roller 10, causing the port 36 to be disengaged from the needle valve 35' and in consequence, permitting the flow of marking fluid from the reservoir 28 onto the brush bristles. At this time, the machine is pushed over the surface to be stencilled causing the wheels 5 thereof to be rotated and in consequence, effecting the transmission of rotary motion by way of the gearing Sand 34 to the bevelled gearing 31 and 30 and thence, to the vertically disposed hollow shaft 26, whereby to effect rotation of the horiontally positioned fountain supply brush in order that the bristles 29 thereof will be movedover the stencil strip and upon being saturated with. the marking fluid, will serve to effectually paint the marking fluid through the openings in the stencil strip upon the surface to be marked. As the machine is moved over a. surface to be stencilled, it will be understood that the stenciling strip will be advanced past the now rotating fountain supply brush, passing from the feeding roller 9 onto the receiving roller 10 and cansing the clock spring 11 within the feeding roller to beplaced under an increasing ten si on. lVith continued movement of the machine over a surface, the movement of the stencil strip by the brush bristles will continue until the stenciling operation is completed, whereupon the several rollers 9 and 10 will have rotated sutiiciently to cause inward travel of their respective pins 22 in the spiral grooves 18 and 18 to points engaging the inner ends of each, whereupon such engagement of the pins 22 with the inner ends of said spiral grooves 18 and 18' will immediately serve to prevent any further rotating movement of the feeding roller 9 and the receiving roller 10, hence, preventing any further removal of the stencil. strip from the feeding roller '9 and in consequence, avoiding disengagement of the previously mentioned inner end of said stencil strip from the roller 9 or the rupturing or damaging of such strip atweith er of its points of connection; However, when the machine is bristles.

removed from the stencilled surface, the

connected thereto and in consequence, it will be understood that that portion of the stencil strip coiled or wound about the receiving roller 10 will be returned to its original po sition about the feeding roller 9 and likewise, that the pin 22 of the rollers 9 and 10 will be caused to travel through the spiral ways or grooves 18 and 18 until they engage the inner end of the same and hence, prevent any further rotative movement thereof, together with the eliminating of any possibility of damaging the stencil strip. Thus, the stenciling machine is ready for a further operation, since with disengagement of the users hand from the hand grip a, the same will be immediately swung to its normal position and likewise, the expansible coiled spring 27 will return the handle 4, and the vertically moveable hollow shaft 26 together with the fountain supply brush to their respective uppermost positions, thereby causing reseating of the needle valve in the discharge port 36 of the brush reservoir 28 and discontinuing the discharge of marking fluid onto the brush bristles 29.

Manifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claims, I consider within the spirit of my invention.
